symfony 5.4 to 6.x || symfony/monolog-bundle": "^3.7.1" issue with UdpSocket

[Khatib-Abbas]

After upgrading symfony 5.4 to 6.x i always get :

NOTICE: PHP message: PHP Fatal error: Uncaught RuntimeException: The UdpSocket to ..XX.. has been closed and can not be written to anymore in /srv/api/vendor/monolog/monolog/src/Monolog/Handler/SyslogUdp/UdpSocket.php:63

My monolog config

        syslogudp:
            type: syslogudp
            host: '%env(resolve:SYS_LOG_UDP_HOST)%'
            port: '%env(resolve:SYS_LOG_UDP_PORT)%'
            persistent: true
            formatter: monolog.formatter.json
            level: info

this current config work very well with symfony 5.4 and monolog 3.5

please try upgrading monolog-bundle and monolog separately to see which one has an issue.

with nx i can easly print some infos on my container "logger" with that command

nc -u logger 6000  

so my container is reachable

I did fix the UdpSocket issue in https://github.com/Seldaek/monolog/releases/tag/2.6.0 so that the socket will reopen on demand, which should fix the issue here.
